Alison was already screaming in ecstasy as her baby boy ravaged her, slamming his cock into the depths of her womanhood hard and fast. She had meant every word she had said to him. People might think that she was in a relationship with Keith, but she was her son’s woman now and forever. No matter how many other women he fucked. No matter if he got married and settled down with children of his own. No matter where he went in the world. She belonged to him, to his cock, and she was his to use whenever he wanted until the day she died.
“Put a baby in mommy, Jason!” she screamed, squeezing the velvet walls of her cunt around his cock.” Mommy wants it so bad! Make me your incest breeding whore! Please baby, please give mommy what she wants!”
It took everything Jason had not to just let himself go and fill his mother’s womb with his seed. Her dirty talk was wearing him down quickly, but he wanted to make sure that she came a few more times before he finished. It was the last time they would fuck for at least a few weeks, maybe months if schedules clashed, and he wanted to make sure that he left his mommy with find memories of her son’s abilities in the bedroom. He pressed his lips against hers, kissing her deeply again, grabbing her arms and pinning them above her head with one hand while his other hand pinched her nipple. He felt her low deep moans in his mouth, and shivering that spread throughout her generous curves as she started cumming again. When her orgasm finished, he slowly pulled his cock from the tight grip of her hole, grinning at her disappointed whimper, and crawled up the bed to feed his shaft between her plump lips. He watched as his mother licked and sucked her own cum juices from his cock, her arms still pinned above her head.
“Tell me how much you love this big fat cock, mommy.” he growled.
“I love it so much baby!” his mother moaned, lapping at his shaft with her tongue between words. “Mommy is addicted to this fat pussy pleaser.”
“Good, because I want mommy to ride my cock until I fill her up.”
He released his mother’s arms and lay down on his back, watching Alison jiggle as she pulled herself on top of him and rubbed the head of his cock on her clit.
“You love it when mommy rides you, don’t you baby?” she asked breathlessly. “You love watching mommy’s fat fucking udders bouncing around. You love feeling mommy’s huge belly smacking against your rock hard abs when she’s coming down on you. Grab my belly and pull me down on your cock baby!”
He did as she said, gripping the soft rolls in his hand and tugging her downwards as she aimed his cock at her cunt and sank down onto it. She got straight to riding him, putting her hands back on his strong thighs and bouncing up and down on his cock like she was in heat. Her belly shook and rippled from the force of their fucking, the soft mass of flesh and fat smacking against her son’s ripped body with a loud clap over and over again. The sight, and more importantly the feeling, of his mother’s BBW body on top of him drove Jason wild. He pulled her down on him, squashing her gigantic tits against his chest. Gripping her ass cheeks, he pulled his legs up to give himself leverage and began to thrust up into Alison’s gushing pussy hard and fast. Mother and son looked into each other’s eyes as they fucked, Jason grunting and panting as he pushed up into his mother’s weight, Alison moaning in pleasure at the strength of her son and how his cock was pounding her depths.
“I’m going to cum, mommy!” he almost shouted, lost in the incredible feeling of his mother’s body weighing him down. “I’m going to put a baby in you, fill you up with my incest cum!”
“Do it baby!” she screamed back. “Put a baby in mommy’s belly, make me your breeding slut! Mommy wants it so bad, Jason! Make your mommy a mommy again!”
With a final thrust of ecstasy, Jason’s hips lifted his mother clear off the bed. His cock, buried as deep as it could go, released a river of incestuous cum to paint the walls of her womb. Although not as intense as the previous two, Alison felt another mini-orgasm radiate out through her body from her now cum-filled pussy. Mother and son collapsed onto the bed again, drenched in sweat and holding each other tightly. Jason stroked his mother’s cheek, brushing her luscious red locks from her face, and smiled.
“You know mom, if Sarah and Sophie weren’t going to be there I think I’d drop out of college to stay here with you.”
“And if your father wasn’t back in the picture I think I’d take you up on that offer.” Alison replied, returning her son’s smile. “I love you, Jason.”
“I love you too, mommy.” he said, kissing her deeply again.
The two lovers fell asleep like that, holding each other in Jason’s bed, until the rest of the family woke them the next morning.

Alison and Keith decided not to accompany their children on the drive back to college. There was barely enough room for the three siblings, plus all their possessions, between Sarah’s car and Jason’s. After several hours playing a real life tetris game with boxes and bags, they were finally able to set off. Sarah would take the majority of her own and Jason’s stuff straight to their new apartment, while Jason drove Sophie to the dorms and helped her get settled in. Dragging out the family goodbyes would only make it harder for Alison and Keith to leave their incestuous lovers. Instead, they waved as their babies drove away and returned to the suddenly very quiet house.
In the car, Jason was struggling to keep his eyes on the road. His little sister was wearing a plaid skirt and fishnet stockings, an almost identical outfit to the day they had first had sex. The only difference was that, instead of a tight t-shirt, Sophie was wearing an oversized hoodie that he recognised as one of his own.
“Are you going to give that back before I drop you off?” he asked.
“I don’t know, big brother,” she said, grinning at him as she grasped the bottom of the hoodie and began pulling it slowly upwards, “do you want your little sister to take your hoodie off?”
He groaned when the button of the hoodie reached her neck. His sister’s petite pale body was on display for him. Not only was she not wearing a t-shirt, she wasn’t wearing a bra either! Her nipples wear rock hard and jutting out from the subtle mounds of her A cup tits, and the sight sent a rush of blood down to his cock.
“I guess you can keep it.” he muttered in frustration, already thinking about when the next chance to pull over would arrive.
“Are you sure, Jason?” she pouted, letting the hoodie drop back over her nubile form. “I can go to college without it, let all those horny boys in the dorms see my tiny little titties, let them imagine their little bounces as I’m being railed…”
“Ok, ok!” Jason groaned. “The next chance I get I’ll pull over and give you what you want.”
“Good boy.” Sophie said, smiling at him and relaxing back into her seat. “Dad and Sarah were lots of fun last night but I was a bit annoyed with mom for keeping you to herself. It’d be different if we were all living together, but I don’t know how I’m going to cope without 24 hour access to that fat fucking cock!”
They drove in silence for a while after that, both of them laser-focused on finding somewhere to pull in and have a roadside quickie. After about half an hour Sophie spoke up again.
“Do you think mom and dad will be ok?”
“What do you mean?” Jason responded.
“I mean, they’ve already got divorced once. What’s to stop them realising that they don’t want to be together again? And what if it’s worse this time because of all the sex with us? What if we end up like those families that have to divide up the holidays between their parents? Mom gets Halloween and Thanksgiving this year, dad gets Christmas and New Year. What if telling daddy about us is going to ruin their relationship for good?!”
Jason could see that his sister was on the verge of tears. Reaching over, he put his hand on her thigh and squeezed gently.
“Ok Elf,” he said, smiling gently at her, “first of all I think you’re just feeling emotional because you’re moving away for the first time. And that’s ok, that’s normal, and it would be weird if you didn’t feel like that. Add in all the other stuff going on with our family, and I’m surprised you’re this calm! But seriously, I don’t think you need to worry about mom and dad. I don’t think they ever stopped loving each other, but I think that they got divorced because they’d lost the spark, you know? And all the incest seems to have reignited that spark, like how some couples open up their relationship after twenty years of marriage and it makes them stronger than ever. Maybe this new spark is just temporary, but even if it is I don’t believe for a second that mom and dad will ever hate each other. They might stop being lovers, though I seriously doubt it after the summer we’ve had, but they’ll always be there for each other and for us. Ok?”
“Ok.” she answered, wiping her eyes. “There’s a side road coming up on your right, let’s see if we can find somewhere private down there.”
They had left the city behind them and were now driving through the suburbs. Soon they found an alleyway just big enough for Jason’s car, flanked on either side by high brick walls that hid them from view of the houses on either side of them. Jason parked the car and Sophie immediately unclasped her seatbelt and climbed into her brother’s lap. Her lips met his in a frenzied and passionate kiss, his hoodie was pulled over her head and discarded in the passenger seat as they made out. She felt his hand slide up her thigh until it found the wetness of her sopping folds.
“Fuck, Sophie.” Jason growled, bringing his damp fingers up to his mouth and licking them clean. “You’re really soaked. And you didn’t wear panties either?”
“I have a pair in my purse.” she moaned in his ear as she ground her dripping crotch on the swelling shaft of her brother’s cock. “I’ll put them on when we’re done to stop your cum leaking out of me. You’re going to need a change of trousers too.”
